Demakein

Demakein is a set of Python tools for designing and making woodwind
instruments.

This generally consists of two stages:

The “design” stage is a numerical optimization that chooses the bore
shape and the finger hole placement, size, and depth necessary for
the instrument to produce the correct notes for a given set of
fingerings.

The “make” stage takes a design and turns it into a 3D object, then
then cuts the object into pieces that can be CNC-milled or 3D-printed.

Demakein can either be used via the command “demakein” or as a
library in Python. Demakein has been designed to be extensible,
and I hope you will find it relatively easy to write code to
create your own novel instruments. You can either create subclasses
of existing classes in order to tweak a few parameters, or create
wholly new classes using existing examples as a template.

Requirements:

nesoni

pip install nesoni

cffi

pip install cffi

numpy

pip install numpy, or apt-get install python-numpy

g++

CGAL

cmake

apt-get install g++ libcgal-dev cmake

Demakein has been tested under Linux. Other operating systems
may require some alterations to make the C++ compilation system
work.

Installation

Easy way

pip install demakein

From source, download and untar tarball then

python setup.py install

You can then run program by typing

demakein

or

python -m demakein

Example

Create a small flute:

demakein design-straight-folk-flute: myflute –transpose 12

demakein make-flute: myflute

Files are created in a directory called myflute.

We’ve just made STL files for 3D printing. How about if we want
to CNC-mill the flute?
